TO ALL'WHOM IT MAY oononnn;

Beit known that I, LUTHER Envmeglof Brooklyn. in the county of Kings, and gtate of New York, have invented certain new and-useful Improvements in Lamp-Burners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specification, in which- Figure 1 is a transverse section of a burner constructed according to my invention, as employed-for heating.

pur oses.

Figure-Q'is a vertical transverse section of a portion of the same, when used for lighting purposes.

Figure 3 is a plan view at one portion of the invention.

Figure 41- is a'plan view of another portion of the same.

Similar letters of reference indicate corresponding parts in all the figures.

This invention is designed either for heating or lighting purposes, and it consists in a perforated top-plate, formed upon the baseof the burner, and situated at the upper end of the wick-tube thereof, in combination with a cup placed over the wick-tube, and an outer foraminated case, whereby the oil or fluid is first converted into vapor within the aforesaid cap, and then'burned'at the top Ofthe'c'a'sejIIs't mentioned, by which means a very perfect combustion of the oil or fluid is secured, and, as a consequence, not only a greater economy of oil or fluid, but also a more brilliant flame and intense heat are obtained, than in the burners of this class hitherto in usei To enable others to understand thenature and construction of my invention, i will proceed to describe it with reference to the drawings.

The base, A, ofthe burner has its sides, a, perforated with numerous small'holes, as represented in fig. 1,

and may be of any desired shape or configuration, and is attached to a. lamp or oil-reservoir, of any suitable construction, in the manner indicated in the red outline in the aforesaid fig. 1. The upper edges of the sides of this base, A, extend slightlyabove the edge of the top-plate b, as shown at a?. The centre of the said topplate is somewhat elevatechor of convex form, and has the upper end of the fiat-wick tube, c, fitted into a suitable opening formed therein for the reception of such end of the wick-tube. This central portion-of the top-plate, b,"on each side of the wick-tube, is perforated with numerous fine or 5135311110163, as shown at a".

D represents u cap, which isdesigned to be made of sheet metal, and the sides of which fire inclined, as

shown in the several figures, nnd'in the top of which is formed a longitudinal opening, d, and which is provided at'its lower edge with a horizontal flanch', d, of such shape that, when the cap D is placed upon the top-plated of the base, A, the said fianch will be fitted within the rim formed by the upwardly-extending edge a? of the sides a of the said'base, and thus hold the cap in position with its opening zisituated immediately over and coincident or in line with the wick-tube c. V I

C shows a case, which is placed over or around the cup D,- asshown in figs. 1 and 2, and which is made of shee metal, perforated with numerous small holes, or of any other suitable foramina-ted material, and which is open at the top, as shown at a. When the burner is used for heating purposes, this case 0 is made to extend considerably higher than the cap D, and has it sidcs,f, but moderately inclined toward each other, as is 'repre sented in fig. 1; but when the burner is to be used for lighting purposes, the top of this case-is but little higher than the top of the aforesaid cap,and its sides are inclined toward each other in positions nearly or quite parallel with the sides of the cap D, when the case is placed over or around the same, as shown in fig. 2. I

A suitable 'wiek being placed in the wick-tube c, with its upper end flush with the surface of the top-plated of the base, as shown in red outline in fig. 1, the case C and cap D are removed, and the wick is lighted, which being done, the cap D is replaced, and becoming heated, by the flame at the upper end of the wick-tube, radiates sufiicient hcatinwurd to volatilise the oil or fuel as fast as it rises in the wick, whereupon the case 0 isi'replaced over or around the cap, and the vapors h eing first mingled with air, that, firstpussing through the perforated sides a of the base, passes up through the holes or perforations in the top-plate 6 enter the case 0, and are lighted'or ignited at the top or opening e of the said case, theflnme being transferred, as it-were, from the top of the wick-tube to the top,of the cap D, and the continued volatilizdtion of the oil from the wick being secured by the inward radiation from the heated cap. I

When the case C is of the construction shown in fig. 1, sufiieient air enters through the perforations of the foraminated material of which it is composed, to insure the perfect combustion of the vapors or gases within the said case, thus producing a very high degree ofvheat, but when the case is of the form shown in fig. 2, as when the burner is to be used for lighting purposes, the flame will be situated at and above'the opening a of the said vcase, the light being in such instance unobstructed by the sides of the said case,-at the sometime that a suflicient quantity or supply of air passes through'the perforated sides of the aforesaid case, to completely burn the vapors or gases, which are thus caused to produce a very brilliant flame, without waste of oil or fluid, so, that, bythese means, a burner capable of being employed with very great economy, for either lighting or heating, is obtained. i

It should be mentioned that, by having the top of the Wick-tube flush or even with the top-plate b, as hereinbefore set forth, the internal capacity of the cap D is increased, and a much more efficient action of the heat, radiated inward. by the sides of the said cap in volatilizing theoil or fluid, is secured, than would otherwise he the ease. "Furthermore, by having the top-plate perforated only at the sides of the wick-tube, a space is left at the edges of the said tube, within the cap 1), for the more perfect expansion and intermingling of the air and vapors within the said'cap, whereby any tendency of the flame to smoke is efi'ectually guarded against.

What I claim as my invention, and desire to secure by Letters Patent, is- 1 The arrangement of the foraminous ease C, cap D, and perforated plate 6, with relation to the wick-tube and base, all combined substantially as shown and described. 1
